Feldspar Chemical composition: All the rockforming feldspars are aluminosilicate minerals with the general formula AT4O8 in which A = potassium, sodium, or calcium (Ca); and T = silicon (Si) and aluminum (Al), with a Si:Al ratio ranging from 3:1 to 1:1. Microcline and orthoclase are potassium feldspars (KAlSi3O8), usually designated Or in discussions involving their endmember composition.
The older isotopic age of the potashfeldspar gneisses agrees with their fielddeduced age of postF2preF3. Muscovite, potash feldspar, and wholerock Rb–Sr analyses show that the Oughterard granite was metamorphosed about 444 ± 7 ago, which is close to the K–Ar age obtained from three hornblendes separated from potashfeldspar gneiss.
Climatic airdity over India 11,000 years ago: evi dence from feldspar distribution in shelf sediments. Palaeogeogr., Palaeoclimatol., Palaeoecol., 53: 309319. Feldspars and quartz contents of sand and silt fractions of forty three samples from the western continental shelf of India were determined by the Xray diffraction method.

The feldspar group minerals are the most abundant minerals in the earth's crust. High concentrations of alumina (Al 2 O 3) and alkalis (K 2 O and Na 2 O) together with low levels of trace elements such as iron (reported as the oxide Fe 2 O 3) define a highquality feldspar adds hardness, durability and resistance to chemical corrosion while the alkalis act as a flux lowering ...
There are two types of feldspar:Soda peldspar(7 percent or higher Na2O) and Potash feldspar(8 percent or K2O).Feldspar silica mixtures can occur naturally, such as in sand deposits, or can be obtaied from flotation of mined and crushed rock. Feldspar is a common raw material int he production of is used for thermoluminescence and ...
3426M Potash Feldspar. Feldspar is a major flux in clay bodies and in high temperature glazes, some of which may contain 70% or more or more feldspar. Potash feldspar is the one generally used and recommended. The term 'potash', 'soda', 'lime' etc. denotes the principal, but not the only, flux present.
